pitoisuushajonta
Pitoisuushajonta, also known as the F-statistic or variance ratio, is a statistical measure used primarily in the F-test of equality of variances. It quantifies the ratio of two sample variances. The F-statistic is calculated by dividing the larger sample variance by the smaller sample variance. A larger F-statistic indicates a greater difference between the two variances, suggesting that the populations from which the samples were drawn may have different variances.
The F-test, which utilizes the pitoisuushajonta, is a common statistical procedure used to determine if there
The distribution of the F-statistic under the null hypothesis (that the population variances are equal) is known
